GIVEN:
QUANTITY A: \(y^2y^4\)
QUANTITY B: \(y^8\)

Simplify Quantity A to get:
QUANTITY A: \(y^6\)
QUANTITY B: \(y^8\)

Let's examine two possible cases:

case i: y = 0
We get:
QUANTITY A: \(0^6=0\)
QUANTITY B: \(0^8=0\)
In this case, the quantities are equal

case ii: y = 2
We get:
QUANTITY A: \(2^6\)
QUANTITY B: \(2^8\)
In this case, the Quantity B is greater

Answer: D
